将Heroku PostgreSQL转储导入本地数据库时出现问题

我正试图将PostgreSQL转储从heroku导入本地数据库（以模拟本地环境中的生产数据）。我正在OSX上本地使用postgres 9.2。以下是我在控制台中采取的步骤：

dropdb db_dev

createdb db_dev

heroku pgbackups:capture HEROKU_POSTGRESQL_MAROON_URL

curl -o latest.dump `heroku pgbackups:url`

pg_restore --verbose --clean --no-acl --no-owner -h localhost -U connorwarnock -d db-dev latest.dump

以及随后的错误：

pg_restore: connecting to database for restore
pg_restore: dropping COMMENT EXTENSION plpgsql
pg_restore: dropping EXTENSION plpgsql
pg_restore: dropping COMMENT SCHEMA public
pg_restore: dropping SCHEMA public
pg_restore: [archiver (db)] Error while PROCESSING TOC:

没有导入任何数据。公共模式似乎导致了问题（我已经手动删除了该模式，然后重试，但没有结果）。也许是hstore扩展造成了麻烦？关于如何避免这些错误还有其他想法吗？

看起来您的

模板1

包含

hstore

扩展以及可能的其他更改

我建议删除

db\u dev

并从

template0

重新创建它，该只读模板包含基本的默认数据库

createdb -T template0 dev_db

如果这不起作用，请在此处发布更新后的错误并发表评论。

请显示您在尝试手动删除

public

然后恢复时遇到的错误<代码>删除扩展存储；丢弃模式公共级联。有一种感觉是hstore造成了麻烦，谢谢修复。
